thanks JFP in PA

now i think i know this answer but with the leak sealed (the leak being a replacement condenser, so not that bad) but with the new condenser in place and everything buttoned up can the car be started w/o refrigerant? or will that just damage the crap out of the ac unit

Coolant: GM designed the precursor to Porsches cognac but at about $15 a gallon. It to was supposed to be a lifetime thing but it intact could start to gum up under certain circumstances. They got sued, straightened it all up and now everybody makes a version of Dexcool (chevron, Pretsone,you name it)..

if you research it you find it meets the requirements of Porsche and for all practical intents and purposes is the same stuff: no silica, phosphates, low ph, etc. Once it was a bit of a secret, now Xerex offers a n improved version which actually list modern Porsche comparability.

Have fun PK

Nice; not even remotely correct, but nice…………..

I changed my coolant this summer when installing the LN low temp t-stat. Purchased the OEM stuff; though a bit pricey, why take chances? Since it gets changed so infrequently, cost really is not an issue.

BTW, I just spent over $30 on Dex-Cool for my wife's Grand Cherokee...Box isn't that much more expensive.

i was thinkin that might be the answer for the coolant, cus it's the same for my audi and to make it last longer mixed in a bit of distilled water to offset the uber high cost

The car can be run without refrigerant, but you should get the system charged ASAP. Whatever you do, do not switch the system on or you will have problems….

The car is smart enough to know that there is no refrigerant (a low pressure cutout switch), so it will not activate the compressor clutch. You can run the car.
